Which of the following is the correct prediction about the three types of model such as; Facilitation, Inhibition, Tolerance model.

#Unit 10. Ecological Principles

Facilitation donot found in the aquatic communities
Facilitation may be important in early seral stages and inhibition important in later once and vice-versa.
Tolerance model exhibit smaller pioneer species would outcompete the larger, slower-growing species
Tolerance and inhibition may both occur in the same community during succession
